soc: qcom: aoss: Add SM8250 compatible

Add SM8250 compatible to the qcom_aoss binding and driver. Acked-by: Rob Herring Signed-off-by: Bjorn Andersson Link: https://lore.kernel.org/r/20200427054202.2822144-1-bjorn.andersson@linaro.org Signed-off-by: Bjorn Andersson

soc: qcom: aoss: Read back before triggering the IRQ

2020-02-14T05:18:16Z

In some device memory used by msm_qmp, there can be an early ack of a write to memory succeeding. This may cause the outgoing interrupt to be triggered before the msgram reflects the write. Add a readback to ensure the data is flushed to device memory before triggering the ipc interrupt.

soc: qcom: aoss: Use wake_up_all() instead of wake_up_interruptible_all()

2020-02-14T05:18:14Z

During the probe the task is waiting in TASK_UNINTERRUPTIBLE state which cannot be woken-up by wake_up_interruptible_all() function. Use wake_up_all() to wake-up both TASK_UNINTERRUPTIBLE and TASK_INTERRUPTIBLE state tasks.

soc: qcom: Invert the cooling states for the aoss warming devices

2019-10-15T03:42:16Z

Thermal framework takes 0 as the lowest/default state for a cooling/warming device. The current code has the order inverted with 1 corresponding to lowest state in hardware and 0 the highest state. Invert this for a better fit with the thermal framework. Signed-off-by: Thara Gopinath Signed-off-by: Bjorn Andersson

soc: qcom: aoss: Add AOSS QMP support

soc: qcom: Extend AOSS QMP driver to support resources that are used to wake up the SoC.

2019-08-05T22:51:09Z

The AOSS QMP driver is extended to communicate with the additional resources. These resources are then registered as cooling devices with the thermal framework. Signed-off-by: Thara Gopinath Signed-off-by: Bjorn Andersson

soc: qcom: Add AOSS QMP driver

2019-06-12T04:52:18Z

The Always On Subsystem (AOSS) Qualcomm Messaging Protocol (QMP) driver is used to communicate with the AOSS for certain side-channel requests, that are not available through the RPMh interface. The communication is a very simple synchronous mechanism of messages being written in message RAM and a doorbell in the AOSS is rung. As the AOSS has processed the message length is cleared and an interrupt is fired by the AOSS as acknowledgment. The driver exposes the QDSS clock as a clock and the low-power state associated with the remoteprocs in the system as a set of power-domains.
